Construction of the temple began in the 6th century BC under the tyrants Hippias and Hipparchos, at the site of the ruins of an earlier temple built by their father, the tyrant Peisistratus. The Temple stood unfinished throughout the ‘Golden Century’ of Athens and was only completed by Roman governor Hadrian, known as the ‘Philhellene’, in 132AD. The Temple was huge by ancient standards, rivalling other colossal famous Temples such as the Heraion in Samos, and featured a large gold and ivory statue of Zeus in its cella. Today, only fifteen of its original 104 columns are still standing. A sixteenth column lies on the ground, where it fell during a storm in the 19th century.
